SpaceIL will be assisted by Sim Dot Space, which will provide a hybrid laboratory and simulator for landing "Beresheit 2" on the moon

The founders of Sim Dot Space Assaf Levin and Amir Nute were responsible for the development of the hybrid laboratory and the digital simulations also of "Bereshit 1" as subcontractors, and were called to the flag to use for the benefit of the challenges of Bereshit 2 with the help of the experience of Bereshit 1

The SpaceIL association has begun a collaboration with the Israeli company Sim Dot Space, within which it will provide a hybrid laboratory and a systemic digital simulation that will enable training "on land" of the Genesis 2 mission. This is a laboratory that simulates the extreme conditions in space in general and on the moon in particular, through which it is possible to carry out comprehensive tests for the "Beresheit 2" landers even before launching the mission into space and to identify how each series of commands will cause the spacecraft to react. SpaceIL's crews will practice operational procedures for landing the landers, while training in troubleshooting and emergency situations.

The founders of Sim Dot Space Assaf Levin and Amir Nute were responsible for the development of the hybrid laboratory and the digital simulations also of "Beresheet 1" as subcontractors, and were called to Degel to use for the benefit of the challenges of Beresheet 2 the expertise they gained both from Beresheet 1 and from civilian and military projects that provided them with simulations since they founded the company in 2019. The company's advanced infrastructure will perform system simulations in real time which will also allow during the mission itself, similar to the Genesis 1 mission, to examine the execution of the series of commands required in the various stages of the mission, by first running them in a laboratory on Earth. In other words, the laboratory considers the real-time conditions of the spacecraft, of the stage it is in during the mission, etc., and only after the laboratory verifies that the series of commands required for the next stage is likely to be received without problems, they give permission to execute the series of commands in real space.

The "Genesis 2" mission is planned to break records in world space history, including a double landing on the moon in one mission and a landing on the far side of the moon, to date only China has managed to land there. In addition, the mother spacecraft, the Mekpet, is planned to continue a long-term mission of about 5 years and will be a platform for scientific educational activity in Israel and around the world, through a remote connection, which will allow students from countries around the world to participate in scientific research in deep space.

According to Shimon Sharid, CEO"To the SpaceIL association: "In order to succeed in making history again, in the challenging mission of Genesis 2, we are using advanced technologies and tools in preparation for the launch planned for 2025. We are happy that Sim Dot Space is joining us on the journey, bringing with it the extensive experience from various projects in the field of space and aviation and experience from the Genesis 1 mission. We learned lessons from Genesis 1, and together we will observe possible scenarios within the framework of the Genesis 2 mission, we will specify the necessary commands in space and prepare for the moments of truth on the best side."

According to Assaf Levin, CEO of Sim Dot Space: "We are happy and excited that the SpaceIL association chose to integrate us into the fascinating project of Genesis 2. The Genesis 1 mission achieved many significant international achievements, including the first private spacecraft to successfully orbit the moon, but as far as we are concerned, the final mission of Genesis 1 "a soft landing of an Israeli spacecraft on the moon" - has not yet been completed. We will do everything in our power to make sure that this time this mission is completed successfully x 2.

Sim Dot Space Founded in 2019 and specializes in the development and establishment of hybrid laboratories, and complex systemic engineering simulations in the field of aviation and space. Levin and Noat have over 30 years of rich experience in the areas of the company's activity in government and civil projects, including the development and establishment of the hybrid laboratory and system simulations of the "Bereshit 1" spacecraft.

  1. Below is a reference for an optimal control problem of landing on the moon. An optimal control problem of the type of the Russian mathematician Pontryagin.

    There are at least dozens of works on the subject. It is very likely that they are known to Man Dhua. Planning a route in advance and a suitable thrust algorithm is necessary.

  2. Hope the friends here will read. From electrical engineering master's degree classes, only simulation is not enough here. Solving problems in optimal and robust control is also necessary here. Without an optimal control solution the probe may crash again.
    It is not enough to see the next step close to real time, but in advance a changing route will be chosen while not crashing.

    If you don't have an optimal control expert, you can consult Professor Amelia Friedman Tel Aviv, Professor Michael Margaliot Tel Aviv.
    I don't study with them. I studied with them. In the landing on the moon, in my estimation, Katherine Johnson from the film Behind the Numbers also developed optimal control equations for the various missions.
